i think it is 14.7 psi. i think one bar 14.7 or atmospheric pressure and 2 bar is double that or 29.4. but 0 psi on you boost guage is atmospheric (spelling) pressure so 14.7 psi on the guage would be 2bar. thats how i understand it anyway.



oops, i was typing as you were. i guess it would be 14.7 at sea level.?. i miss read the question too. he said kpa not psi lol. oh well.

Cool, Thanks! So it looks like a 2 bar should be good for ~17.5PSI up hear at 7000'. Since we are at 78KPA atmospheric pressure it would take +122 KPA to get to 200. 122 KPA is 17.7 PSI correct?

Same difference. I have to start off with 11.2 PSI of air pressure up hear. I have to make 3.5 PSI of boost just to get to where you guys start off. So to equal 14PSI of boost down there I would have to make 17psi up hear. About 15PSI is all my turbo will make hear so the 2 BAr should be perfict.

Yep, actually you can get a bit more out of a 2 bar then 2 bar, it just runs a little rich from when the sensor get maxed out, till it get to your peek boost, since you will tune your AFR for your peak boost number, if that makes since,

Cool! So can I tune it the same way as I due when the MAF is maxed out? Just keep adding fuel X RPM, after sensor is maxed out?

Yep! If you were gona run 20 psi, it's not like it's gona spend much time at 17-19.9 anyway.
